Common Name The Ochre-Yellow Catasetum

Flower Size 3/4" [2 cm]

Found in Colombia on flat rock slabs, sandstone, disturbed forests and forest edges at elevations of 100 to 1700 meters as a small to medium sized, hot to cool growing, lithophyte, epiphyte or terrestrial with fusiform to ovoid pseudobulbs subtended by leaf bearing sheaths and carrying 2 to 3 apical, plicate, narrowly elliptic leaves that blooms in the summer and fall on a basal, erect, 20" [50 cm] long, racemose, several flowered inflorescence arising on a mature pseudobulb.

This species needs light to moderate shade and can take some cooler temperatures and even though in nature is most often a terrestrial/lithophyte it can be potted in bark media.

Related to Catasetum bergoldianum which occcurs in a much lower elevations mainly 50 to 400 meters and differs primarily in the height and depth of the labellum [2:3 instead of 5:4] and the convergent antennae and the much shorter antenna length as well as the much wider [1/2"] petals.

Synonyms Catasetum inornatum Schltr. 1915; Catasetum lehmannii Regel 1886
